CamExpert is Qcad + some Cam stuff, including Gcode generation.
I found that the GCODE generated by this program had some issues that
prevented it's use -- specifically, it didn't use enough decimal places
to satisfy EMC about the endpoints of arcs.
Also, I haven't found ANY program that optimizes the tool path. As you
know, when cutting foam, you can't stop in the middle, lift out the wire
and re-start cutting somewhere else. You have to make one continuous
cut. Most of the Gcode programs assume you have a Z-axis that you can
use to lift your cutting head and reposition it. Codeg matches
endpoints so that it's one continuous path.
Be sure you read the README file WRT compiling -- you'll need the Boost
development headers / libraries.
